Is it just a insubstantial that comes on when tire pressure drops significantly? Or does it actually report to you which tire is dangerously low?

Answers: in that are sending units contained by each reins that work on radio wave frequencies. they can be simple, lately to turn on a light, and it's up to a human to determine which one, or, surrounded by more upper end cars, they can specifically communicate you which tire. usually they will work when the tire is more than 6 psi too low, but that varies between brands.since we don't know what genus of car you have(a little info would enjoy been nice) this is a 'nutshell' explaination of the system. your owners encyclopaedia can explain it further.

Depending on the vehicle, it will tell you specifically which tire is low or that you only have a low tire, but it doesn't give an account you which one.
